Those who loved and knew Paul Walker paid tribute to the late actor on Monday, Dec. 2. After attending a private memorial service in Santa Clarita, Calif., the movie star's Fast and the Furious costar Vin Diesel made an impromptu speech in Valencia using a sheriff's car's microphone.

Calling Walker his "brother," the 46-year-old action star thanked attendees for their support in light of the actor's Nov. 30 passing. "At this hard time his family gets to see all of you show the love that you've shownPaul. It's going to stay with me forever," Diesel said. "I just wanted to say thank you. Thank you for coming down here and showing that angel up in heaven how much you appreciate him."

On Sunday, Dec. 1, Tyrese Gibson arrived at the crash site to pay his respects. Walker's Fast & Furious 6 costar carried a yellow lily with him and took a piece of the wreckage home with him.

Walker, 40, died when Roger Rodas' limited edition Porsche crashed Saturday afternoon. The car was engulfed in flames and both men died on the scene; autopsy results are pending. The two had spent the afternoon at a car show and toy drive set up through Walker's charity, Reach Out WorldWide.
